IMPROVEMENT IN ANNUNCIATORS.

Specification forming part of Letters Patent No. 178,297, dated J une 6, 1876; application filed November 28, 1874.

To all whom it may concern:

Be it known that we, FREDERICK HIRSOHY, HENRY L. KORTE, and HERMAN F. AcHAUER, of the city of Zanesville, in the county of Muskingum, in the State of Ohio, have invented a new Hotel Room-Indicator, with keyboard attached; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in attaching, by a bar, a bell to an indicator, and in attaching to the indicator a key-board.

Figure 1 is a perspective view of our improved indicator, showing the exterior of the same; Fig. 2, a plan or-g top view, with the upper part of the casing removed to show the operating mechanism; Fig. 3, a perspective view of the dial indicator-bar, with number attached; Fig. 4, a detached view of the lever and springs; Fig. 5, the catch and spring of the door-indicator.

This invention has relation to that class of devices known as hotel room-ind icators;

and the object of the present invention is to produce an indicator simplein construction and perfect in its operation, the same having attached a bar, bell, and key-board, in connection with the several operating devices, which will be hereinafter described, and subsequently pointed out in the claim.

In the drawings, Ais designed to represent ahorizontally-sliding bar, to one end of which are attached a bell-wire and bell of any suitable form or construction. The bar A is operated by a wire, Q, said wire being connected to pivoted levers E K, causing them to press on attachment H, fastened to the bar A, thereby springing the indicator and exhibiting the 7 number of the room or place from which the call is made.

shown in Fig. 5. A dial-bar, M, may also be employed, when found necessary, in place of the bolt-indicator D, or the door-indicator,

as above described, the same operating mechanism being employed in each alternative device.

The reactive power is furnished to the levers E K by springs F, the samepower being furnished to bolt-indicator D by'spiral spring G, to door-indicator P by spring 0, and to dial-bar M by spring I. A brace, L, forms a guide for the spring F.

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination, with an indicating-plate, bolt, or dial-bar, having a suitable catch and spring, as described, of a horizontal bar, A, carrying attachments H, and the pivoted le-. vers E K, with springs F, the spring B, bellwire 0, and bell R, substantially as and for the purpose set forth.
